The stars of the new film join some of the gorgeous gals from the ‘Sports Illustrated Swimsuit Issue’ for the NYC premiere!

It may be cold in NYC, but one would never be able to tell based on the very fine, and barely there, wears of the ladies at the Cinema Society screening of writer and director Josh Radner‘s debut film, happythankyoumoreplease. The film’s stars, Malin Akerman and Zoe Kazan, went short for the night: Malin in a red strapless dress and Zoe in a light blue one-shouldered look with cutaways, both by the evening’s sponsor, Tommy Hilfiger.

Also spotted were Swimsuit girls Irina Shayk and Chrissy Teigen, Irina putting to rest pregnancy rumors in her form fitting Herve Leger dress.

Following the screening, Ed Westwick, John Mayer, Carey Mulligan, Adrian Grenier, and Amar’e Stoudemire headed to the 18th floor of The Standard, New York for the flick’s after party. Guests also spotted sipping Woodbridge by Robert Mondavi wine at the fete included producers Austin Stark and Bingo Gubelmann from Paper Street Films, Cinema Society Founder Andrew Saffir, Lily Rabe and Catalina Sandino Moreno.

The film, which was first shown at the 2010 Sundance Film Festival, will be released March 4.

So HollywoodLifers, who do you think looked best at the happythankyoumoreplease premiere?
